In the last few years Palangka Raya City was hit by many points of forest and land fires (Karhutla) that have sprung up intentionally or not sporadically which resulted in smoke and an unpleasant atmosphere which would trigger material losses and of course the health of the surrounding community that inhaled the smoke left over from forest fires and the land. This condition also results in health, economic, social and environmental losses which will certainly hamper the pace of development and the ongoing development of the City of Palangka Raya. The main objective of this research is the use of drones to detect and community preparedness for forest and land fire disasters in areas that have potential for forest and land fires.

Peat swamp forests serve as an abundant water catchment area in rainy season and then releases it gradually in dry season. The main function of peat swamp forests are as the hydrology regulator in an ecosystem, and the function will be disrupted when the peat swamp forests have excessive drainage condition. Recently, the peat swamp forests of Central Kalimantan are badly damaged by prolonged exploration without any responsibility to preserve it. One of the damage causes of the peat swamp forests in Central Kalimantan are many canals made when illegal loggers get their harvested wood out to the estuary of nearest watershed. Therefore, it forms canals that drain water with no control. The effect is peat swamp forests will be very dry and trigger devastating fire that cannot be extinguished in a short time. One of the efforts to deal with the problem is by recovering the hydrology condition of peat swamp forests ecosystem through duct insulation using simple dam locally called â€œtabatâ€. The making of tabat is easily designed in order that the implementation is not very hard, and the material selection such as forest wood dominate the construction because the wood will be cracked gradually without disturbing the ecosystem process and restoration principle in peat swamp forests. The modeling result by a computer software of hydraulics shows the increase of water level in canals at 15 to 30 cm and the width of inundation in tabat when the designed flood of two-year return period was modeled to 280.67 km2 and for the period of five years was 306.04 km2 from the target of hydrology restoration of 250 km2.

The main function of peat swamp forests are as the hydrology regulator in an ecosystem, and the function will be disrupted when the peat swamp forests have excessive drainage condition. Recently, the peat swamp forests of Central Kalimantan are badly damaged by prolonged exploration without any responsibility to preserve it. One of the damage causes of the peat swamp forests in Central Kalimantan are many canals made when illegal loggers get their harvested wood out to the estuary of nearest watershed. Therefore, it forms canals that drain water with no control. The effect is peat swamp forests will be very dry and trigger devastating fire that cannot be extinguished in a short time. One of the efforts to deal with the problem is by recovering the hydrology condition of peat swamp forests ecosystem through duct insulation using simple dam locally called “tabat”. The making of tabat is easily designed in order that the implementation is not very hard, and the material selection such as forest wood dominate the construction because the wood will be cracked gradually without disturbing the ecosystem process and restoration principle in peat swamp forests. This study was one of the efforts to rescue peat swamp forests by hydrology restoration using a modeling concept with a computer software of hydraulics. The modeling concept used steady flow water surface profile to find out the capacity of cross section to designed flood. After the simulation, tabat modeling was then made to the height of canal. The modeling process resulted in the width of inundation in tabat. The height of water level and the number of tabat were required to optimally inundate the research area. The modeling result by a computer software of hydraulics shows the increase of water level in canals at 15 to 30 cm and the width of inundation in tabat when the designed flood of two-year return period was modeled to 280.67 km2 and for the period of five years was 306.04 km2 from the target of hydrology restoration of 250 km2. The modeling of inundation width in tabat of peat swamp forests will be suggestion for the government of Central Kalimantan Province and the stakeholders in building a big scale tabat.

Measuring air retention in constructed canal blockage is critical for determining changes in air content after canal blocking. The purpose of this study is to assess the influence of changes in levels on air retention values measured at three depths, namely 0-20 cm, 20-40 cm, and 40-60 cm, at four transect sampling stations created at a distance of 10 m to 260 m from the canal block. Changes in bulk density, porosity, and peat volume affect groundwater. Peat soil samples were collected from burned peatlands, and canal blocks were constructed. A pressure plate chamber was used to assess air retention. The findings of the investigation revealed that the air retention pattern of peat soil at 16 test sample locations was at maximum at PF 0.2 at each depth. At higher pressures (pF 2-4.2), peat groundwater is strongly bonded by peat soil particles. The average bulk density of peat is 0.2 2 and the porosity value is 86.79%. The higher the air content at each pF value has no influence on the porosity and bulk density values. Changes in air content between pF 2.0 and 4.2 lower average peat volume by 7.4%. The size of this value is assumed to be determined by the peat's type, maturity, and decomposition value.

Land and peat forest fires in Indonesia are a serious environmental problem, especially in the years that experience the El Nino phenomenon. El Nino causes dry and hot conditions that trigger fires. One of the methods used to extinguish fires is water bombing, which is spraying water from the air using planes or helicopters. The purpose of this study is to analyze the effectiveness and efficiency of the water bombing method in dealing with land and peat forest fires in Indonesia. This study uses secondary data from various sources, such as government reports, research institutions, mass media, and non-governmental organizations. The data is then analyzed using descriptive, comparative, and evaluative methods. The results of the study show that the water bombing method has some advantages, such as fast, flexible, and able to reach areas that are difficult to access. However, this method also has some disadvantages, such as expensive, risky, and less effective in extinguishing fire in the peat soil. Therefore, this study recommends that the water bombing method should be used as one part of a comprehensive fire control strategy, which involves prevention, detection, and recovery. This study also suggests the need for improved coordination, regulation, and innovation in the use of the water bombing method in Indonesia.

One of the elective courses in the Building Engineering Education Study Program, FKIP, Palangka Raya University is Bridge Structure. Experimental study is a way of teaching and learning that involves student activity by experiencing and proving for themselves the process and results of experiments which are closely related to everyday life. On the subject of bridge structures, it is necessary to carry out experimental studies on bridge pillars. Pillars are part of the bridge's lower structure. The existence of pillars in river flows causes changes in river flow patterns. Changes in flow patterns will result in local scouring around the pillars. This research aims to determine the effect of pillar shape on the potential for local scour that occurs around the pillar. This research was carried out under steady uniform flow conditions with three discharge variations. The physical models of pillars used are rectangular pillars, cylindrical pillars and triangular pillars. The type of research used is experimental research. The research location was carried out at the Building Engineering Education Laboratory, FKIP UPR with glass channel media with dimensions of 200 cm long, 15 cm wide and 20 cm high. In the test with flow discharge Q1= 40.08 cm3/sec, the maximum scour in the middle of the pillar that occurred was (ds)= 0.2 cm and the average at the edge was (ds)= 0.3 cm for pillars with the shape rectangular, while for triangular and cylindrical pillars experiencing sedimentation, Q2= 100.20 cm3/sec. The maximum scour at the center of the pillar that occurs is (ds)= 1.3 cm and the average at the edges is (ds) = 1.4 cm for rectangular pillars, while for triangular and cylindrical pillars experiencing sedimentation, Q3= 107.04 cm3/sec. The maximum scour in the center of the pillar that occurs is (ds)= 1.5 cm and is flat -average at the edge is (ds)= 1.5 cm for pillars with a rectangular shape, while for pillars with a rectangular shape and cylinders experience sedimentation. The results obtained from this series of research are that the greater the discharge flowing in a channel cross-section, the deeper the local scour around the pillars will be and the best shape in this study is a cylindrical shape because it has the potential for the smallest scour depth.

Fish farming is a promising business alternative, especially in rural areas such as Petuk Liti Village. With the potential of existing natural resources, good management is needed so that cultivation results can be optimal (Iskandar & Muslih, 2022). One important aspect of fish farming is controlling water quality, especially water level, which affects fish health and growth (Rahmadani, 2021).However, the challenge faced by fish farmers is the difficulty of monitoring water levels in real-time, so that decisions are often made that are not appropriate, which can be detrimental to cultivation results. Therefore, this PKM activity aims to develop a water level monitoring station based on remote camera technology (GSM) which is implemented in Petuk Liti Village, Pulang Pisau Regency, Central Kalimantan.The monitoring station designed in this research consists of several main components, including a monitoring camera, a water level sensor, and a GSM module which functions to transmit data.The output target of this service is expected to make a significant contribution in increasing the efficiency and effectiveness of fish farming in Petuk Liti Village. With a monitoring station, farmers will be quicker and more accurate in taking the necessary actions, so that cultivation results can be optimal.
